Title: Method of recovering edta from waste liquor of edta
Inventor: YOSHIDA TADASHI
IPC: C07C67/00
Filed: 1985-10-28
Abstract: PURPOSE:In adding an acid to waste liquor containing EDTA to adjust the waste liquor to a specific pH and to crystallize EDTA as a free acid, to advantageously recover EDTA from the waste liquor, by partially feeding the waste liquor from the bottom of a crystallizing tank to fluidize seed crystal of the free acid. CONSTITUTION:An acid is added to waste liquor containing ethylenediaminetetraacetic acid(EDTA), the waste liquor is adjusted to <=3pH and EDTA as a valuable substance is crystallized and collected from the waste liquor such as waste liquor of chemical plating, etc. as a free acid(H4Y). In the operation, the waste liquor adjusted to <=3pH is partially fed from a bottom 9 of a crystallizing tank 2 charged with seed crystal 3 of H4Y, the seed crystal 3 is fluidized by an upward cocounter flow, simultaneously the waste liquor sent from a bottom 1 to carry out crystallization and the seed crystal 3 of H4Y having desired, grown particle diameters is taken out from a bottom 10. By this method, since the particle diameters of H4Y crystal can be continuously and efficiently enlarged and EDTA can be recovered as approximately spherical high-purity crystal, the following washing and dehydrating processes can be made efficient and simplified and improvement in recovery ratio can be contrived.

Title: Method and apparatus for cutting semicured mortar
Inventor: OKUBO HIDEAKI
IPC: B28B11/14
Filed: 1996-09-11
Abstract: PROBLEM TO BE SOLVED: To reduce the adhesion of mortar to a blade body, to check the deterioration of cutting performance, and to make the properties of a cut surface improved by cutting semicured mortar by a cutting means in which blade bodies are installed intermittently in the longitudinal direction of an endless belt which moves around or in the circumferential direction of a rotary disk. SOLUTION: When an auxiliary cutting means is moved horizontally to follow a cutting means which is transferred by a traveling means, a roller cutter 4a rotates clockwise by the resistance of a substrate 1 and cuts the uncut part (m) of a mortar block while rotating and pushing it. Since the distance between blades of the cutter 4a is slightly narrower than the clearance between cut surfaces formed by cutting blades fixed intermittently, both outer surfaces of the cutter 4a contact the cutting surfaces, and cutting and separation can be done with the properties of the cut surfaces of the mortar block M improved.

Title: Waveform equalizer
Inventor: OKAMURA TAKUMI
IPC: H04N5/21
Filed: 1992-09-09
Abstract: PURPOSE:To surely process waveform equalization by preventing especially signal clip at an input of an A/D converter due to transmission line distortion at AM transmission when the transmission line distortion caused at analog transmission is eliminated through the use of a reference signal. CONSTITUTION:The equalizer is provided with a multiplier 11 multiplying an output signal of an A/D converter 3 by a multiple of alpha to obtain an m-bit digital signal and its output is fed to a synchronization/data detection circuit 10 and an equalization filter 4. Furthermore, the equalizer is provided with a low-order bit passing circuit 12 passing low-order n-bits in an output signal in m-bits from the equalization filter 4. When a waveform equalization control means 15 controls a multiple alpha of the multiplier 11 at AM transmission, the synchronization/data detection circuit 10 controls an AGC amplifier 2 to decrease an amplitude of an input signal to the A/D converter to 1/alpha. Thus, the A/D converter 3 does not clip the input signal and the reference signal representing the transmission line distortion is accurately detected and the equalization filter 4 is controlled accordingly.

Title: Ghost eliminator
Inventor: MORIMOTO YOUICHI
IPC: H04N5/21
Filed: 1983-12-20
Abstract: PURPOSE:To improve the ghost eliminating performance and also to shorten the ghost eliminating time by stopping the setting action for a tap coefficient of a transversal filter at a time point when the ghost is reduced down to satisfactorily small degree. CONSTITUTION:An output is produced at a counter 15 when ZN<-1> times of correlative operations needed in a maximum ghost mode is through. Then a maximum value deciding circuit 16 is triggered by the output of the counter 15. The circuit 16 monitors the maximum value of the tap coefficients of each stage of a transversal filter TF 2 which is stored in a tap setting memory 14. Then the actuation of an arithmetic circuit 13 is stopped when the tap coefficient value is changed to a decrement from an increment. Thus each tap coefficient set by an immediately preceding correlative operation is held in the memory 14. Hereafter the ghost correcting signals are produced in response to each tap coefficient and the ghost is eliminated.

CONSTITUTION:In performing copying, the photosensitive drum 11 receives light with the aid of a pre-transfer exposer 18, and a destaticizing electrode 16 destaticizes by AD bias. After the drum receives weak yellow light with the aid of a pre-electrifying exposer 19, the electrifier 12 electrifies positively.
